To all whom it they conceive:

Beit known that l, ANTHONY avc1t1zen of the United States,residing at a Los Angeles, in the county ofLos Angeles and State of California, have invented'certain new and usefulImprovements, in a Stone DrillingMachine, of' which the following is a specification; i i

My invention relates a to ;a drilling machine, and facing machine tool apparatus, and is directedparticularly to a tunnel horing machine which 1nay; be used to drillthr'ru stone or other hard substances.

\ ,Theobject of thisinvention .is toprovide StQIlBfiglELSS, or softer materials.

a simple, compact itoolwhich may be used in a boring or ifacing machine to cut thru nu h h n-c ie t to plr v d a d fll g machine that will bore tunnels, by remow ingqua tity etaate ia aroun 8/ central 5 core with multiple rotary cutters.

To operate the machine the cylinder 26 is first placed on the rails 30, and anchored in the bore 1 by the clamps 28, the edges 33, 33 or 33 on the cutters 3, 3 or 3 respectively are then made to bear on the surfaces 31,'the motor 25 is then set into motion to turn the frame 29 and yokes 6 thereon, by

transmitting the power thru the gears 13 and 14, shaft 40, and gears 15 and 19 respectively. The frame 29 turns in the cylinder 26 by rolling on the wheels 12 over the rails 27, and is in turn held in its longitudinal position within the said cylinder 26 by rolling on the wheels 11, over the said rails 27. To remove the solid rock or other materials in the bore 1, the edges 33, 33* or 33 on the cutters 3, 3 or 3 are fed into the surfaces 31,

as the frame 29 turns in the cylinder 26, by

' screws 5, a new cutting position will be necessary, thus tores ume a new cutting operation the gear 15 is first removed out of mesh with the gear 19, the posts 4 are in turn withdrawn from the surfaces 31 by reversing the rotation of the screws 5, by throwing the gear 17 into mesh With the gear 13 by the lever 23, the motor25 is again set into motion and the power is transmitted therefrom thru the gears 13, 17 and 16 respectively, to the screws 5 as hereinbefore described.

When the posts 4 have been withdrawn from the said surfaces 31 to their desired position for the new cutting position, the apparatus may be advanced further into the I bore 1, and around the core'2, by moving the cylinder '26 on the rails 30, and the cutting operation thru the surfaces 31 may be repeated.

When the core 2 attains a length convenient. for handling it may be broken ofi' for its disposal.

The hollow 34 in the cutter 3 is best adapted to roll the edge 33 into the line 42,-

on a line parallel with the center line of v the posts 4, when in its angular position as shown'in Figurefi; the flat face 35 in the cutter 3 is also best adapted to roll the edge 33?;into the bevel surface 31, on a line parallel with the centerline of the said posts 4,

when in its angular position; and the diamond edge 33 in the cutter 3 will trim the sides of the bore 1 and core 2 without binding on the sides thereof, when being fed into the surface 31 on a line parallel with the center line of the said posts 4.

When the edges 33, 33 and 33 are fed into the surface 31, a new surface line 31 will be reached, after the'stone or other material has been broken away, as illustrated in Figures 5 and 6, by wedging thru the said surfaces 31 with a rolling-motion, and forcing the loose and broken materials therefrom.

Having thus fully described my invention, 1 claim as new and desire to secure by Letters Patent 1 1. In an apparatus for cutting rock, the

combination of a supporting frame, adapted to be secured over the surface of the said rock, a revolving frame operatively positioned in the said supporting frame, a tool post operatively positioned in the said revolving frame, a power transmission means, adapted to guide andcfeed the said tool post, a pluk atively positioned in the said revolving frame, a power transmissionmeans, adapted to turn the said revolving frame, and feed the saidtool posts, a plurality of rotary,

cutters operatively positioned on the, said tool posts at predetermined angles, adapted to break away and remove the said rock, as set'forth.

' 3. In a tunnel boringmachine, the combination of a cylinder, adapted to be secured in the bore of a tunnel, a frame operatively positioned in the said cylinder, around acentral core, a power transmission means, adapted to revolve the said frame, a plurality of tool posts operatively positioned in the said frame, a feeding means, adapted to operate the said tool posts, cutter heads positioned on the said tool posts, a plurality of rotary cutters, adapted to be positioned at predetermined angles bearing radially towards the center of the said bore and core,v

and also tilted at predetermined angles from the longitudinal line of the saidtool posts, as set forth. v

In testimony whereof I aflix my signature.
